('08-'10) why does car misfire and then run fine?

bradze · 06-23-2010, 11:15 PM

i may be incorrect about the misfire part, but it stutters occasionally and then runs fine. this has happened about 4 times when i accelerate and nothing seems to happen except the stutter. wife said it stalled on her one morning. i just find it weird that it didn't throw a code. are there any problems with the coilpacks on these or something like that? could it just be the E3 sparkplugs ive been using for the last 20k miles? if i went to a stealership i wonder if they'd even find anything....

do you have an aftermarket blow off valve? sounds like a vacuum leak

bradze · 06-25-2010, 01:18 AM

of course not, its normally aspirated

scoobyoutback73 · 06-25-2010, 11:14 AM

oh ok i missed the na part

bradze · 06-29-2010, 11:11 PM

it broke down yesterday, cost $82 for a tow. sat overnight at Pacific Import Auto in spanaway, wa (anyone with a subaru in the NW will probably recognize that name) and this morning they looked at it and couldn't find anything. i drove 30+ miles with no problems. problem wont throw a code so who could find anything. im sure a stealership will tell me the same thing. my wifes powertrain warranty is up in 1500 miles.

maybe i'm misunderstanding you, but i had a couple cars with issues like this (not as new), which were bad selenoids and choked fuel injection system-- or so I was told. I ended up getting rid of both of them while they were running.

bradze · 07-01-2010, 01:19 PM

just told her trade-in value, thats not an option. which solenoids?

Strobe Media · 07-01-2010, 03:32 PM

maybe your coil packs are going bad? maybe bad injector sensors, weird ass spark plugs....could be a number of things

i'm sorry i don't remember. it was a camry, they were little black and yellow metal and plastic blocks looked a lot like a bike pedal. there was a crack in the yellow part, which they claimed caused intermittent misfire and stalling. (not a gearhead)

I got the Impreza not long after.

bradze · 07-11-2010, 11:08 PM

well i changed spark plugs and its been fine since, but subaru recommends changing every 30k so i was gonna change anyway....

bradze · 03-28-2011, 10:38 AM

i was wrong, not spark plugs. same problem is back, id get rid of car but we're so upside down on loan, guess ive been putting too much attention towards tracking my evo, my infant daughter, school, should of helped her pay off...

bradze · 03-28-2011, 12:31 PM

found some other stuff about imprezas randomly stalling, no one seems to have an answer though, same as me mechanics find nothing
